Dieppe's Revenge

The Battle of Dieppe was a costly operation for the Allies. Of the approximately 6,000 men who took part in the raid, over 3,600 were killed, wounded, or captured. The Canadians, in particular, suffered heavy casualties, with many taken prisoner.
Despite the high cost of lives and equipment, the Dieppe raid provided valuable lessons for the Allies. They realized the importance of better planning, coordination, and intelligence gathering for future amphibious operations. These lessons were applied in the planning of the successful D-Day landings in Normandy in 1944.
